DKIM Record Checker
Check that your DKIM record is published, valid and uses a strong key. Not sure of your selector? Leave it empty and we will look for common ones.
What is DKIM?
DKIM adds a digital signature to every email you send. The matching public key lives in your DNS at selector._domainkey.yourdomain.com, and receiving servers use it to confirm the message really came from you and was not changed on the way.
How do I find my selector?
Your email provider tells you. Google Workspace usually uses google, Microsoft 365 uses selector1 and selector2. You can also open the headers of an email you sent and look for s= inside the DKIM-Signature line.
